  1. 223 case neck separation

    You really need to post a picture. Brass normally fails closer the the base, about 1/3 of the way up leaving much of the case in the chamber. This is the portion of the case where the heavy base thins. Sizing brass too much will do this as will excessive headspace. Other potential culprits can be brass that's too long or burrs in the chamber.
  2. Expander ball vs M die

    There are a thousand ways to load ammo and they are all "Right" I would suggest that the proof is in the pudding; you should evaluate a sample of ammo before you run a large batch. I have loaded quality ammo with all kinds of dies and set ups and brass is usually the largest contributing factor for runout, I have some 7.62 LC91 that sucks no matter what I do. Total indicated runout or variations in case measurements (not headspace, that's inside the rifle) can be indicators that you have problems that could be a bent decapping rod or not getting enough lube inside the case necks. I try to load 10 rounds and check the runout on each one as well as put them into a case mic, if everything is still set up right, runout will be low and shoulders will be in the same place
  3. Expander ball vs M die

    I have tried all kinds of dies. Unless you are turning necks you really need an expander ball with bushing dies to provide the most consistent neck tension without turning necks which is a no-go for three gun. Otherwise your id will vary with brass thickness. there is really not a downside to using an expander ball with Redding dies. An m die will work about as well. the advantage the Bushing dies will provide is that you're not working the brass as much but you still need to end up with an id that's .221-.222 for a semi auto or about .002-.003 neck tension.
  4. Inconsistent neck expansion with Lyman M Die

    Your problem is that your setting up your trimmer so that it's not trimming all cases. You want to set up your trimmer for the short side 1.750 or the trim to length, not the long side. If you did find that your shortest cases are 1.752, then you could set up your die for that as well. You will get some variation in OAL because you are using range pick up brass. It happens. You should also have set up your sizing die so that it's sizing all the cases not just some.
  5. How does one know if we got into the match or not?
  6. accuracy of 223 on a progressive

    when I was shooting NRA LR more I loaded all my 1k ammo on a 550. I still load a little here and there with it. I use a powder die from a 450 in the powder station and pause on the down stroke to dump in powder and then onto bullet seating.
  7. 3 gun rule; shooting over a prop, now what

    How about striking a prop within xx ft? Would that make a difference?
  8. accuracy of 223 on a progressive

    No, a better barrel is not going to make wolf shoot much better. I've tried wolf and privi out of several Krueger barreled service rifles and it still sucks. Years ago ago when you had to shoot mil-ball 7.62 NATO in Palma competition guys did work to find what they could do to get bad bullets to shoot better. They did find tight bores and odd grove barrels and slow twist rates would shoot bad bullets better. You can buy 55 FMJ ball for like 300.00 per k and that's going to far outshoot the cheap Russian stuff. Proper copper jackets will also make a barrel last longer than shooting bimetal steel bullets.
  9. accuracy of 223 on a progressive

    There is a huge difference among "bulk ammo". The Russian stuff is mostly junk, I have tried a few boxes out of a few guns and it just plain does not shoot well. Most of the other 55g FMJ stuff shoots ok to pretty good depending on the mfg and the lot. Most of your accuracy is dependent on bullet selection. There is no standard for match anything. Your never going to get a junk bullet to shoot well. I've had no luck getting the privi "match" ammo to shoot for example and the hornady 55 fMJ shoot much better than some others.
  10. 3 gun rule; shooting over a prop, now what

    The shooter had to really really really stretch to take the shot from where he did. While I'm not sure it was intentional or not, there was not really "a good shot" from that position or anything close to it. I appreciate the call.
  11. 3 gun rule; shooting over a prop, now what

    How do you stake down a barrel on top of another barrel? - understand range equipment failure and reshoot would be the best call.
  12. Lock back with rounds in mag

    if your bolt is sticking to the rear: - The first place to always check are the magazines, ammunition and lubrication. If your magazines are gummed up or the ammo is a little dirty, the bolt can have a hard time stripping a round out of the magazine. - Provided the all else is good, you really need to take a look at the malfunction in action to determine where the bolt is in relation to the ammunition. If the bolt is almost all the way back and it's "stuck" about 1/4-1/2" forward from the base of the case it's likely your system needs a little more energy to return the bolt all the way to the rear of the magazine IOT pick up a fresh round of ammo. Again, improper lube, under power ammo or bad magazines can contribute to this. Provided those are OK, open up your gas block a little more and see if that fixes the problem.
  13. Lock back with rounds in mag

    You need to identify if the bolt is locking back as in the bolt catch is engaging OR the bolt is flailing to strip a round out of the magazine and is stuck back. If you pull the magazine out and the bolt goes home, your bolt is stuck back. If you remove the magazine and the bolt remains locked to the rear, your bolt is locking back.
  14. No Go Gauge for Firing Pin Hole for AR15 Bolt?

    It could have helped if you included what the problem was first. Yes, if your having pierced primers, blow primers, or primer flow etc issues then yes Firing pin hole could be an issue. An oversized firing pin will not help with this particular issue. This is is also why ppc and some other caliber rifles have "small firing pins". You are able to run a little hotter with less of a chance of pierced primers.
  15. There is no reason to get a SB die unless you have an undersized body portion of the chamber. Some company standard dies are smaller than other company's SB dies. A bushing FL die will not size as far down on the case neck as a standard FL die will.
